CALGARY, ALBERTA, June 20, 2017 – Critical Control Energy Services Corp. (“Critical Control” or the “Corporation”) (TSX:CCZ) is providing an important update to the proposed plan of arrangement (the “Plan of Arrangement”), the details of which are contained in the information circular dated May 26, 2017 (the “Information Circular”) mailed to all shareholders of record as of May 25, 2017 for the Corporation’s Annual and Special Meeting of Shareholders to be held on June 29, 2017.

Under the proposed Plan of Arrangement, all registered shareholders must return a properly completed Letter of Transmittal and Election Form to Computershare Trust Company of Canada in accordance with the instructions contained therein prior to the Election Deadline of 10:00 am (Mountain Standard Time), June 27, 2017.

Any shareholder who holds their common shares in a brokerage account, must contact their broker to advise their election such that the broker can complete the Letter of Transmittal and Election Form on their behalf prior to the Election Deadline.

Shareholders may either elect to:

exchange all or a portion of their Common Shares for a new series of Preferred Shares on the basis of 0.0775 Preferred Share for each Common Share held (the “Share Exchange”), up to the aggregate maximum of 29,992,500 Common Shares (the “Maximum Conversion Shares”), subject to proration; or

exchange none of their Common Shares into Preferred Shares (the “Status Quo Election”).

No fractional Preferred Shares will be issued; the nearest whole number of Preferred Shares will be issued, with fractions equal to 0.5 or more being rounded up.

Shareholders who elect to make a Share Exchange and who would receive fewer than 100 Preferred Shares on the exchange of their tendered Common Shares will receive a cash payment of $0.155 per tendered Common Share (the “Cash Consideration”).

Shareholders who fail to submit a Letter of Transmittal and Election Form and who hold 1,290 or fewer Common Shares will automatically receive the Cash Consideration (the “Minor Shareholders”).

If fewer than the Maximum Conversion Shares are voluntarily tendered for exchange pursuant to the Share Exchange, all of the Common Shares of holders who either: (i) failed to submit a Letter of Transmittal and Election Form (other than Minor Shareholders); or (ii) failed to validly make the Status Quo Election for all of their Common Shares (“Non-electing Shareholders”), will be exchanged for Preferred Shares on a pro rata basis until the Maximum Conversion Shares limit is reached (the “Automatic Share Conversion”).

If an Automatic Share Conversion is required, Non-electing Shareholders who receive fewer than 100 Preferred Shares on the pro rata exchange of their Common Shares will receive the Cash Consideration and will not receive Preferred Shares. If a Non-electing Shareholder receives the Cash Consideration, its redeemed Common Shares are excluded for the purpose of calculating the Maximum Conversion Shares.

If a registered Shareholder does not want to be subject to the Automatic Share Conversion, they must ensure that Computershare Trust Company of Canada receives their Letter of Transmittal and Election Form prior to the Election Deadline.
